Soa-based Enterprise Application Integration Framework To Study

This paper aims at problem of the current study of enterprise application integration ignoring business process integration, integrated ability is bad, flexibility is poor, and interoperability is not very well and so on. So we propose Enterprise Application Integration Architecture based on SOA(Service- Enterprise Application Integration), which is advanced in loose-couple, low cost, high integration ability, etc. The main topic of this paper is about the architecture of the EAI based on SOA, and it's model and the service.The development of software is accelerated by Service Oriented Architecture at present, which can be regarded as the revolution using modularized and loose coupling application procedure replace singleness and close coupling ones. This article mainly aims at problems of the current study of enterprise application integration that includes neglecting business process integration, bad integrated ability, poor flexibility, bad expansibility and so on. So we proposed an architecture based on SOA—S-EAI(Service-Enterprise Application Integration), which is advanced in loose-couple, low cost, and high integration ability, etc. The main topic of this paper is about the S-EAI, and it's the model and service of different layers. At first, a systematic survey of EAI management research is given, and the study objectives of this thesis are presented.Secondly, we analyzed the excellence and disadvantage of the traditional technique of EAI. And then we proposed the challenge and difficulty EAI faced. We adopt the advanced technology SOA, then we proposed the architecture of the EAI based on SOA, which can support the modern flexible IT infrastructure for enterprise and show the reuse and flexility of the system.We proposed the enterprise foundation architecture lamination model based on the definition and classification of enterprise application services, including users'interface service, shared business service, message and agent service, and shared application service.The shared application service, the shared business service and the message and agent service are included by the infrastructure services. In the part of shared application we mainly introduce the application interface service, and describe two kinds of adapters the system supports, and propose the formalized definition adapter model. The message and agent service is correspondence service layer of the system, which is the concrete realization of distributed architecture. And we propose message object model based JMS and the realization of the two kinds of message mechanism. The sharing application service mainly give the support to the process flow, and enables to be convenient to the enterprise complex changeable process flow by carrying management of the key services in the process of producing or running .Based on these infrastructure services, the paper give the classification of the process under the S-EAI, describes the enterprise service flow modeling, arranging and carrying out...
